I have a subscription but I am seeing the 3- or 6-article limit notification, what is going on?
If you are seeing the 3-article limit message, please make sure you have created an account and are logged in. If you are logged in and are still seeing the 6-article message, please confirm that the account you created is using the same email address that is associated with your subscription. If you are still seeing the message, please submit a ticket via our contact form.
I am subscribed for digital magazine delivery. How do I access my full-issue PDF?
If you are logged into your account, you will see a link to the full-issue PDF at the top of each issue’s table of contents page on the PT website. If you are signed up for PT newsletters, you will receive an email at the beginning of each month linking you to that month’s issue page.
You also have access to full-issue PDFs dating back to 2019, which you can find in the Issue Archive.
How do I change my mailing address or cancel my subscription?
If you receive PT through your membership in one of the professional societies in the AIP federation (AAPM , AAPT , AAS , ACA , AMS , APS , ASA , AVS , Optica , and SoR ), please contact that society to update your subscription information.
If you have a direct subscription to PT, you can update your information on the Account page or by submitting a request to our contact form.
